Senior UI/UX Designer (f/m/x) - Product & Experience

Senior UI/UX Designer (f/m/x) – Product & Experience

ilert – Cologne, North Rhine-Westphalia, Germany

Overview

ilert helps thousands of DevOps and IT teams, from fast‑growing scale‑ups to global enterprises, detect, understand, and resolve incidents before they impact customers. Our platform powers always‑on operations, and we are building the next generation of agentic systems: an AI SRE agent that learns from telemetry, reasons about incidents, and autonomously assists engineers during critical moments. As our first dedicated Product Designer, you will define the UX foundation for this new paradigm, owning the end‑to‑end design of complex, high‑stakes workflows and translating deep understanding of our technical audience into intuitive interfaces for both web and mobile.

Location

Hybrid – Cologne (Rheinauhafen) – 3 days a week in the office, 2 days remote (Tue and Thu)

Team

Product • Reports to the CEO • Partners with Engineering team

Discover & Define

• Conduct user interviews, workflow analyses, and problem‑framing sessions to deeply understand DevOps/SRE personas, their mental models, and operational pain points.
• Translate insights into clear problem statements, user journeys, and design hypotheses.
• Collaborate with Product and Engineering to define success metrics for usability, comprehension, and incident‑response efficiency (e.g., MTTR, triage accuracy, alert fatigue reduction).

Design & Develop

• Design end‑to‑end user experiences, from low‑fidelity sketches to high‑fidelity prototypes that express interaction flows, progressive disclosure, and edge‑case handling.
• Develop new UI/UX paradigms for agentic workflows, including conversational interfaces, action recommendations, autonomous task previews, and human‑in‑the‑loop validation states.
• Create data‑dense dashboards, timelines, RCA views, and real‑time surfaces that balance clarity with depth.

Deliver & Iterate

• Provide detailed specifications and partner closely with engineers during implementation.
• Validate designs with qualitative feedback loops (user testing, product analytics).
• Operate with pragmatic startup speed: accessibility and A/B testing are welcome skills but not top‑priority constraints in this role.

Requirements

• 3+ years designing production SaaS interfaces end‑to‑end
• Portfolio that proves user‑centric thinking, visual craft and shipped impact
• Mastery of Figma (auto‑layout, variants, tokens) and basic motion/animation
• Hands‑on with design systems, component libraries and responsive layouts
• Fluency in English (our working language); German is a bonus
• Solid grasp of HTML/CSS limits and possibilities – enough to speak dev

Bonus Points

• Designed for technical audiences (DevOps, SRE, cloud engineers)
• Exposure to real‑time data products or event‑driven interfaces.
• Experience designing AI‑powered workflows (assistants, copilots, agent interfaces).
